I was thinking the same way but Wsquared58’s posts make me worry. I start to see particles and fumes everywhere now.

Did you see the trend from the Blue ABS Benchy?
I have some sensors that require a higher voltage than the MCU’s can provide alone.
Those are particulate sensors and in addition to the VOC sensors the particulate sensors paint an ugly picture of the environment inside the P1S enclosure.
